I have a lot of nutsedge growing throughout my perennial peanut groundcover. How can I eliminate it without killing the groundcover? I keep pulling it out but it grows back twice as thick. I bought a spray product at my local HD but it didn't do anything to either the ground cover or the nutswedge.

Nutsedge is really difficult to control because it develops underground roots (nutlets) that will remain in the soil if you pull the plants out. You actually need to dig the weeds out, making sure you get all the little nutlets in the soil. There are some herbicides that will control nutsedge but they are not safe to use around all kinds of ground covers so you'll need to read the list of plants it is safe to use on the label of the product. A product containing bentazon such as Monterey Nutsedge Killer will control the weed; Image Nutsedge killer and Weed Stop Weed Killer for Nutsedge are other options. Be sure to check the labels to see if they list perennial peanut groundcover as safe to use the product on. Repeat applications may be necessary. Good luck with your eradication project.
